Lhermitte-Duclos disease is a rare disorder characterized by a slowly enlarging mass in the cerebellum. The exact nature of this lesion remains unclear, but it has been variously characterized as hypertrophy, hamartoma or benign neoplasm. Single-photon emission computed tomography (SPECT) with (123)I-iomazenil and (99m)Tc-ethyl cysteinate dimer (ECD) display central benzodiazepine receptors tha...

Lhermitte-Duclos disease (LDD) is a benign neoplasm of posterior fossa, involving cerebellum. It is also known as dysplastic cerebellar gangliocytoma. It is not a true neoplasm but a hamartoma. It can be either isolated finding or associated with Cowden (multiple hamartoma syndrome). adults.

Lhermitte-Duclos disease was first described in 1920 in the literature under the names of Purkinjeoma, granular cell hypertrophy of the cerebellum, hamartoma of the cerebellum, dysplastic gangliocytoma, ganglioneuroma, and gangliomatosis of the cerebellum. Patients tend to be young adults and may present with signs of cerebellar dysfunction or increased intracranial pressure secondary to obstru...

Lhermitte-Duclos disease (dysplastic gangliocytoma of the cerebellum) is a rare benign cerebellar mass of unknown etiology which is characterized by enlargement of the cerebellar folia. Despite the controversy regarding its pathogenesis, imaging and histopathological findings are rather typical. A 17-year-old female presented with a 2-year history of progressive headaches and gait imbalance. Cr...
